Alton, you didn't chicken out; there was just no more gas in the tank after bb. Had you had energy you wouldn't pass the opportunity, with your memories of pistol river and 1000 windsurf sessions under your belt.
It was just 1.3m and I have seen windier conditions where Ambleside it's just unsurfable (it was not the case last Sunday).
Next time, NW will probably hit 1.6m, switch to your windsurfing gear and give kitesurfing a hiatus, just follow the light.
